One step into the cave, and the hot steam blocks all view and envelops your whole body. Be guided forward by the bubbling sounds you hear from deep inside and you'll realize the source of the vapors and sounds is a hot spring. Found during the Nara period, Hashiriyu is a spring source in a horizontal tunnel, which number only a few across the whole country. It is said that in the past, about 900 liters of hot spring water flowed rapidly down towards the sea every minute. This is one of the three oldest and largest hot springs in Japan and has been carefully maintained from ancient times as a sacred spring. The stunning views give a real sense of the mountain energy that seems to gush out with the hot water.
※ Views like the one shown in the photo can only be seen under certain conditions (time of day, weather etc.).
Adults may have to stoop down in the cave since the ceiling is low. Please walk slowly as the steam reduces visibility. People may get sweaty since the cave is so humid and hot inside. Also, please be careful not to get too close, since there is no fence and the water is about 70 °C hot.
